Letters Patent No. 95,564, dated October 5, 1869.

IMPRQVED SPRING-BED BOTTOM.

The Schedule referred to in these Letters Patent and' making'part of the same.

To -all whom it may concern,.-

Yonkers,kin the county of VVes'tchester, and State of' New York, have invented Va new and useful Improvement in Spring-Bed Bottoms, of which the followingy is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure l represents a plan view of a spring-bed bottom, constructed in accordance with my improvement; Figure 2, a sectional view of 4a portion of the lower frame;

Figure 3, a sectional elevation through one of the braces to the lower frame, showing the springs as united by the clamp;

Figure 4, a plan view in part immediately' above one ofthe lower clamping-disks;

Figure 5, a top view of a lower clamping-disk to the springs; and

Figure 6, a longitudinal section through one of the slats in part.

Similar letters of reference indicate corresponding parts.

My improvement has reference to that description ofspring-bed bottoms in which the slatsare made to rest upon Atransversely-arranged flat springs, supported or' carried by spiral springs that rest upon a lower main frame.

My invention, in this connection, consists in a novel union of the spiral with the transverse flat springs, by means of divided disk-clamps with intervening packing, the lower'halfor portion of the clamps lying under half-or portion of said clamp.

By the use of this clamp, with its intervening packing or packings, a' much irmerandsteadier bearing is es tablishedfor the bearing ot the tlat transverse springs upon the spiral ones, and all noise or rattle consequent upon the friction of the springs, and which has heretofore been so objectionable a teature in spring `bed bottoms of' the character described, isavoided.

Referring to the accompanying drawing- A A represent the cros'sbraces oi' .the lower main frame B.

Upon these cross-braces, at suitable distances apart, are located the spiral springs U.

The upper ends of these springs are bent'down, as at a, and the leg thus formed caused to pass through a hole, b, made in a lower -clamping-disk, D, which has a groove, c, formed in its upper surface to receive the top coil of said'spring, that thus has aiirm or steady bearing against it.

The several spiral springs C, having been thus entered within and fitted to their respective lower clamping-disks D, a paper or othe suitable soft packingpiece, d, is laid upon each of said disks, over the coil of the spring C, embedded therein, upon which packings the transverse dat springs E ofthe bed-bottom are made'to rest.

Fitting over the clamping-disks D, so as to hold the springs E between them, are corresponding disks, D', having paper or other suitable soft packing-pieces, d', arranged between such upper disks and said springs E, so that the latter are held between the two soft packings d d'.

-Snch upper disks, D', it is preferred to form with recesses, e, o n their under side, to give them clip or hold onthe springs E, and prevent the clamps, as formed by-the disks D and D', from turning.

Rivets, f, pass through the disks D D', springs E,

and packings d d', to establish the clamp and union of the spiral with the transverse Hatsprings.

lhe slats F that occupy an intermediate position-to the spiral springs, I prefer to connect" with the Hat' springs E, by means of screws g, resting on copper washers h, which latter and the heads ot the screws are let into recesses, t, made in the slats, the bodies of the screws passing through the slats and through suitably-buried holes in the springs E, or nuts may be fitted on to the screws below said springs. Rivets may be substitutedfor these screws g if desired.

A springfbed bottom thus constructed will be found durable, free from rattle or noisevof the spiral with the transverse springs, may be packed for transportation in a small compass, and dispenses with the use of' exible straps to hold the slats at suitable distances apart.

The clamps, as formed by the disks D D', also give a'much steadier action to the springs, without impairing their elasticity.

What is here claimed, and desired to be secured by Letters Patent, is-

The combination, with the slats F, the transverse f lat springs E, and the spiral springs O, arranged in lrelation to each other as described, of the spirally- Witnesses I nnn. HAYNER, HENRY PALMER.
